[size=5][sub]I would say, based on history, that its inevitable, at some point, that certain models will be more desirable than others. Take the '82 Fullertons, or even the '82 JV's for example. I would firstly choose a bass you can enjoy playing, that suits you, then choose something more limited than a 'regular' issue. A Custom Shop model would probably hold its value more than a standard, but will it increase? For example, a regular Custom Shop Relic has been around the £1500 mark S/H now, for the last 7 years, with a rarer, more limited version being around £2k. Thats probably more a sign of the economic climate though, than anything else, although 70's Fender basses have more than doubled in the same period. Tells a story i think. Are they better basses?, not for me, but you asked about investment.[/sub][/size]
